Explanation of error
Why philosophers mistakenly thought of the soul as immaterial.
And for the matter, or substance, of the invisible agents, so fancied, they could not by natural cogitation fall upon any other concept but that it was the same with that of the soul of man; and that the soul of man was of the same substance with that which appeareth in a dream to one that sleepeth; or in a looking-glass to one that is awake; which, men not knowing that such apparitions are nothing else but creatures of the fancy, think to be real and external substances, and therefore call them ghosts; as the Latins called them imagines and umbrae and thought them spirits (that is, thin aerial bodies), and those invisible agents, which they feared, to be like them, save that they appear and vanish when they please. But the opinion that such spirits were incorporeal, or immaterial, could never enter into the mind of any man by nature; because, though men may put together words of contradictory signification, as spirit and incorporeal, yet they can never have the imagination of anything answering to them: And therefore, men that by their own meditation, arrive to the acknowledgement of one Infinite, Omnipotent, and Eternall God, choose rather to confesse he is Incomprehensible, and above their understanding; than to define his Nature By Spirit Incorporeall, and then Confesse their definition to be unintelligible: or if they give him such a title, it is not Dogmatically, with intention to make the Divine Nature understood; but Piously, to honour him with attributes, of significations, as remote as they can from the grossenesse of Bodies Visible.
